If I recall correctly, SS produces 2nd order distortion ( not pleasing to the ear ) While tubes produce 3rd order distortion ( pleasing to the ear ) 3rd order distortion is close to the distortion your would get by running you fingers across the strings of a guitar for instance.
I started out looking for SS gear, then decided to try a SS amp with a tube pre. Then eventually went all tube. I have never looked back. Now if I stop by a audio shop that happens to be playing anything on SS it sounds, like finger nails on a chalk board.
If you like the sound of tubes, why worry about getting that last octave of bass?
